I have a Porcher Sink that was shipped to me from a company that went out of business and now I fine that it has the European Sized Opening.
My Sink is an Overflow Sink, and my Hardware is Toto Soiree tl960sd chrome, which ofcourse is American Sized. Where can i get a drain or flange to fit?????

Thanks, I have tryed everything, hours on the internet.
